ALGEBRA CHECK ANSWERS
Solve each equation by graphing the related function. If the equation has no realnumber solution, write no solution.
NOTE: when I write + it has a minus on the bottom too
x^2+7=0
a. x= +7
b. x = +3.5
c. x= 0
d. no solution ***
3x^2=0
a. +3
b. +1/3
c. 0 ***
d. no solution
1/4x^24=0
a. x=+3
b. x=+4 ***
c. x=+2
d. no solution
Solve each equation by finding square roots. If the equation has no realnumber solution, write no solution.
4g^2=25
a. g=+1/2 ***
b. g=+1/3
c. g=+5/2
d. no solution
64b^2=16
a. b=+1/4
b. b=+1/2
c. b=+1/8 ***
d. no solution
144p^2=0
a. p=+14
b. p=+6
c. p=+12 ***
d. no solution
5z^245=0
a. z=+3
b. z=+1/3
c. z=+9
d. no solution ***
Tell how many solutions this equation has
h^2=49
a. one solution ***
b. two solutions
c. no solution
s^235=35
a. one solution
b. two solutions ***
c. no solution

Some are ok. I have listed the errors below
> 4g^2=25
your answer solves 4g^2=1
> 64b^2=16
your answer solves 64b^2=1
> 5z^245=0
5z^2 = 45
z^2 = 9
z = ±3
> h^2=49
see your solution to x^2+7=0
> s^235=35
s^2 = 0
...
Are you trying to take shortcuts in your head? These are all pretty straightforward, if you just take the proper steps.posted by Steve
